Per- and polyfluoroalkyl substances (PFAS), volatile organic compounds, biogeochemical, and water quality data from seep samples, Lower Darby Creek Area Superfund Site, near Folcroft, Pennsylvania, 2024 ...

This metadata record contains one table and one shapefile with results from field sampling at locations of groundwater discharge (seeps) identified by autonomous boat survey at the Lower Darby Creek Area (LDCA) Superfund Site, near Folcroft, Pennsylvania, in 2024. Included in the dataset are (1) PFAS concentrations, volatile organic compound (VOC) concentrations, cations/trace metals data, total organic carbon (TOC) content, anion concentrations, dissolved gas concentrations, total and ferrous iron concentrations, sulfide concentrations, water quality measurements, and their associated field sampling information for porewater samples collected from seeps and (2) water quality parameters (pH, turbidity, dissolved oxygen, specific conductance, and water temperature) and coordinates measured in creeks in LDCA by a remote-controlled autonomous boat as part of seep identification surveys. ...
